The Sun Certified Developer for Java Web Services 5 (SCDJWS) certification exam (designated CX-310-230) is for developers who have been creating web services applications using Java technology components such as those supported by the Java Web Services Developer Pack, JAX-WS and JAXB. Other topics like XML, JSON, REST and security are covered too.
There is an older version, SCDJWS 1.4 (designated CX-310-220), which is still available, but some of the covered topics are now obsolete (e.g., the JAX-RPC API has been replaced by JAX-WS).
The pre-requisite for this certification is that the candidate should be a Sun Certified Programmer for Java 2 Platform (any edition). There is no dedicated book available for the exam.
